The role of a Medical Science Liaison (MSL) is a critical one in the pharmaceutical industry. As the bridge between pharmaceutical companies and healthcare professionals, MSLs facilitate the exchange of scientific information, contributing to advancements in patient care. In this blog post, we will explore how to succeed in this role in 2023.

Understand Your Data

In the era of big data and artificial intelligence, the ability to understand and interpret data is more crucial than ever for MSLs. MSLs often communicate with highly intelligent individuals, including professors and researchers. Therefore, it’s essential to know your data well to communicate effectively and confidently. This not only enhances your credibility but also enables you to contribute valuable insights during discussions.

Effective Time Management

Time is a precious commodity, especially in the fast-paced world of healthcare. Effective time management is a key success secret for MSLs. This involves planning your meetings, sticking to agreed topics, presenting your data effectively, and following up on any actions or questions. In 2023, with the increasing use of virtual meetings and digital tools, managing your time effectively will be even more important.

Know Your Audience

Knowing your audience is a timeless principle that remains relevant in 2023. Do background checks on clinicians and academics you’ll be speaking to. This could involve understanding their published work or local audits they’ve presented. With the wealth of information available online, doing your homework can help you engage in more meaningful and personalized conversations.

Maintain Integrity

As an MSL, you are a representative of your company and it is paramount to maintain your integrity. This means providing accurate information, respecting the time of healthcare professionals, and never taking advantage of your position. In 2023, with increasing scrutiny on pharmaceutical practices and transparency, maintaining integrity will be even more critical.

Embrace Failure

In a rapidly evolving industry, trying new ideas and learning from mistakes is essential for growth and innovation. If you have new ideas, don’t be afraid to bring them up and try to implement them. If they don’t work, learn from it and don’t do it again. In 2023, with the pace of change accelerating, this ability to learn from failure will be a key determinant of success.


Succeeding as an MSL in 2023 requires a combination of technical knowledge, interpersonal skills, and a growth mindset. By understanding your data, managing your time effectively, knowing your audience, maintaining your integrity, and embracing failure, you can excel in this role. Remember, as an MSL, you are not just a representative of your company; you are a scientific expert, a trusted partner, and a crucial link between your company and the healthcare community. Embrace these roles, and you’ll be well on your way to success in 2023.
